Update Policy

Registering any program with Black Cat Systems allows you to not only use the version of the program that you've registered, but it also allows you to upgrade to the newest versions of the program for one full year. This means that for the year after registering a program, you may download and use any new versions of the program free of any additional charges.

Once your registration year has ended, you will still be able to use the program you have registered indefinitely. But, you will not be able to download and use new versions of the software without re-registering.

As an example: I download Diet Sleuth and like the program, so on 2/15/2000 I register version 2.2.0 for $25. In a couple of months, I see that there is a new version of Diet Sleuth. So, I download version 2.3.0 of Diet Sleuth and begin to use it with no extra cost to me. Throughout the year, occasionally there are new releases of Diet Sleuth, and I would download them and use them in the same manner. So, say that on 2/15/2001 I am using version 2.5.0 of Diet Sleuth. The program works fine, and I am happy with the program. On 3/1/2001, Black Cat Systems releases version 3.0.0 of Diet Sleuth. Because the registration year has ended, I would not be able to download and use version 3.0.0 free of charge - I would have to register that version of Diet Sleuth in order to use it. But, I would be able to continue using Diet Sleuth version 2.5.0 for as long as I want. If I chose to register version 3.0.0 of Diet Sleuth, I would again receive a full year of upgrades to new versions of Diet Sleuth.

Below are buy it now buttons for all of our programs that have reduced pricing for renewals. Just click on the button and you will be taken to PayPal, where you can pay for your renewal. You must use this page for the special pricing, if you place an order on the regular order page, you will be charged full price.

Usually we can supply your new registration code in about one day, sometimes in just a few hours.

Purchasing renewal/update will allow you to use all versions of the program released within one year of your update purchase date.

Please be sure to download and fully test the new version prior to purchasing an update, as we cannot provide refunds.
